The Wilder Ranch State Park is a day-use state park, historic site, and recreation area in Santa Cruz, California. It features a series of former ranches.

Considered as a hidden gem in the city, the Wilder Ranch State Park offers a great amount of things to see and do. For one, it is packed with historic structures which are originally components of the old ranches. One is the rancho adobe, an 1897 Victorian farm house as well as other structures. Some of the buildings are now used as a museum.

Composed of seven thousand acres of land area, the Wilder Ranch State Park is a great spot for mountain biking, hiking, picnicking, and horseback riding. Spelunking is also a popular activity inside the park, although cavers here do not want the word to come out about it.
